Single-Phase Motor Performance-A New Approach

Reliable equations of performance for the single-phase induction motor are obtained in terms of the angles between the stator and rotor mmf (magnetomotive force) waves. This results in a new method of approach and yields a new form of impedance locus. The expressions for slip, current, and torque in terms of these angles are derived and the results obtained by this method are compared with the test results and with those obtained from the equivalent circuit.
